Application filed September 23, 1910. Serial No. 583,338.

` To all whom it may concern;

Bc it known that l, WILLIAM K'. Annexe son, a subject ot' the King of Denmark, residing at. Riclnnond Hill, city of New York.

boi-nigh of Queens, inthe county ot' Queens and State of New York, have invented certain new and useful"improvements in Carbureters, of which the following is a. full, clear, and exact specification.

o My invention relates to means for producing explosive mixtures from hydrocarbons or other liquid fuels adapted for use as a inotivep'ower for explosive engines, and the same has for itsl objectniore particularly to provide a simple, eflicient and reliable apparatos whereby a properly proportioned explosive inixture may be readily produced andr maintained.

Further, said invention has for its object to provide-a carburetor which may 'be easily and conveniently adjustedlor regulated to produce and maintain said properlyproportibned explosive mixture.

Further, said invention has for ,its object to provide la carburetor in which the air supply may be easiy and conveniently'adjusted to meet the requirements of the motor under varying conditions o ,.operation.

Further, said invention has for its object to provide a carburetor in which the auxiliary air vulve is so constructed and'arranged that; the saine can be easily and conveniently regulated either by adjusting the'valve and its support or bushing directly, or by adjusting the valve indcpendently'of its support orbushing.

To the attainment of the aforesaid objects and ends, my invention consists in the novel details of construction and in the combination, connection-and arrangement of parts hereinafter more fully described, and then pointed out in the claims.

ln the accompanying drawings, forming part of this specifica-tion, wherein 'like numorals ofl reference indicate like parts,

Figure 1 is a side 4View showingope' form 'of carburetor constructed accordingl to, and embodying my said invention; Fig. 2 is a longitudinal section taken on the line. 2 2

of Fig. 3.- Fig. 3 is a plan or top View;

Fig. tis an enlarged detaill cent-ral section `taken partly on the line 2-2 of Fig. 3, showing a portion of the carburetor casing with the means .for controlling or regulating the auxiliar air supply to the' carburetor;

Fig. 5 is aA etait cross-section taken 011 the line 5-5 of Fig. lv showing the construction of the valve stt-xn and tht` nuan's` for actuating-:the saine, and lig. (5A is a detail crosssection taken on the lino 6 6 of Fig. 4 showing a portion of the means for securing the valve stein and `valve to its adjusted position. i

ln said drawings, the carburetor is shown comprising a flat, horizontal ('asing'lO provided upon its upper side-adjacent to one end with a tubular outlet 11 having a flange l2 at its upper end for securing the carbureterto the inlet pipe or manifold of a motor.

13 denotes a throttle valve pivotally mounted in vthe outlet l1v upon a shaft 14, and provided at one end with an operating lever 15, and atits opposite end with a stop 'mont of said throttle valve 13.

In the bottom ofthe horizontal casing 10,

directly below the outlet l1, is provided a threadedopening within which is secured a 'tube 19 having its Haring end extending into said casing 10. The said tube 19 is provided upon its outer side with an annular flan 2() adapted to engage the under side of the 'casing 10 to limit the inwardA movementI of said tube 19while the same is being, secured within said casing.

21 denotes a short tube section arranged vertically within the lowerV portion of the tube 19 and secured thereto by a short horizontal tubo section 22.

23 denotes a conical nozzle secured to the upper end of said vertical tube 2l `and eX- tending into the constricted end of the tube 19, and in the lower end of said vertical tube 21 is secured a screw 24 which serves as a closure for the lower end of said tube, and which screw 24 is adapted to be removed therefrom to facilitate' theucleaning ofthe nozzle 28. y 25 denotes a. circulai'tloat casing which is provided in its base With a centrally located threaded aperture adapted to be screwed upon the lower end of the tube 19 whereby to bring the upper edge of said float casing 25 into contact with the under side of the horizontal casing 10 and inclose said tube.

The float casing 25 is provided at one side with an oti'set port-ion 26 which communi# cates et its lower end with a source of gasolene supply. Within said offset portion 26 annularj float' 2 8.' arran ed ithin the 'casing .25 and surrounding t e.tube l9. A t the outer end of said 'lever'4 27 is pivotallyvfsecured a valve stem' 29 having a valve/30 'at its lower"end adapted to control the supply' of gasolene to the `float easing 25.

.The operation of the carbureter. is as f ollows: Gasolene is'admitted inthe usuallmln- 'ner through the inlet 55 and controlld'by the valve 30 through themedium of the ver -29'nnd ont-`28 'arranged within the oat- 10'5- casing`25. As soon as-tlhe' throttle valve is opened-.and the motor 'set in operation', a1r will. be.'drawn primarilv through the open lever end'of 'the tube 1 9, and mixiwith a 1 certain n'mount of gusolene issuing; trom' the 11o'- 'Qonical nozzle extending! into the constricttionincreases, owing to the increased speed' ofthe motor, air will be. drawn into, the i cnsi'gl() through' the auxiliary inlet formed i415 'by Vthe 'bushing 35, -and ,pss between"thief'-Y .lower-edge of saidfbnshing and the valve 39 seatingt-hereom Theactionof the valve is initially controlled by' the' larger and comesgreater and. moreainmust be drawn into the carbiireter, the valve 39 .will be 'openstill further,. and nsit- 'continu'esto descend it will engagev the upperfend of the spring Weuk'erspring 48, and asA thefsuction .be- 12o 41 disposednpon the'lower'ond ofthe valve .12%.

stem 38 and thereupon .the 'downward or opening-movement -0it.he valve-'will be yieldingly resistedfor the remainder of its 'movement by 'the -eonihined action of the springs 41 and 48.# The opening I novement1'3'0- of valve 39Ais primarily controlled by the spring 48, and the tension of this spring maybe increased or diminished by rotating the bushing -35 within its threaded opening. As soon as the bushing 35 has been adjusted to the desired position in order to obtain the required tensioning of the valve 39 the ball 54 will automatica/ily spring into the recess 51 nearest thereto in the fiange 50,- and thus serve to-hold the bushing with its valve to the adjusted position. The further action of the valve 39, as it opens wider under the increased suction of the motor, is controlled by the small spring 41 disposed upon the lower. ,end of. the valve stem within the larger spring 48. The amount of movement accorded to the valve'Q upon the stem 38 under the ylesser resistance of the spring '41 is controlled byrotating the'nut 42 and the valve'stem 38,`Which being ln'threaded engagement vwith the vertical bearing 37 is caused to riseor descend' accordingr to the `direction in which the nut 42 is turned.

`. By turning the nut 42 to the left, the distance between the under side ofthe valve 39 and the upper end of the spring 41 is increased, and'by'turning the nut 42 to the right the distance diminished. fr As soon as the desired adjustment has been obtained, the spring 46 upon the upper nut of the valve stem 38 will cause the projections 43, 43 on the under side of the nut 42 to,

spring into the recesses 44, 44.provided in the upper side of the bearing 37, and thus serve to hold the parts to their adjusted position.

It will be noted that in my improved carbureter I am enabled to easily and conveniently'adjust the auxiliary air supply to suit the conditionsof loperation under low speed as Well as under high speed by merely turning the bushing 35, or by turning the nut 42 arranged upon the valve stem 38, which control the primary resisting spring 48, and the secondary resisting spring 41, respectively.
